Whey I try to run magnum service-list to list all services (seems now we only have m-cond service), it m-cond is down(which means no conductor at all),<br>
API won't response and will return a timeout error.<br>
<br>
taget@taget-ThinkStation-P300:~/devstack$ magnum service-list<br>
ERROR: Timed out waiting for a reply to message ID fd1e9529f60f42bf8db903bbf75bbade (HTTP 500)<br>
<br>
And I debug more and compared with nova service-list, nova will give response and will tell the conductor is down.<br>
<br>
and deeper I get this in magnum-api boot up:<br>
<i><br>
# Enable object backporting via the conductor<br>
base.MagnumObject.indirection_api = base.MagnumObjectIndirectionAPI()</i><br>
<br>
so in magnum_service api code<br>
<br>
return objects.MagnumService.list(context, limit, marker, sort_key,<br>
sort_dir)<br>
<br>
will require to use magnum-conductor to access DB, but no magnum-conductor at all, then we get a 500 error.<br>
(nova-api doesn't specify <i>indirection_api so nova-api can access DB</i>)<br>
<br>
My question is:<br>
<br>
1) is this by designed that we don't allow magnum-api to access DB directly <span style="font-family:"Calibri",sans-serif">
？</span><br>
2) if 1) is by designed, then `magnum service-list` won't work, and the error message should be improved such as "magnum service is down , please check magnum conductor is alive"<br>
<br>
What do you think?<br>
<br>
P.S. I tested comment this line:<br>
<i># base.MagnumObject.indirection_api = base.MagnumObjectIndirectionAPI()</i><br>
magnum-api will response but failed to create bay(), which means api service have read access but can not write it at all since(all db write happened in conductor layer).<br>
<br>
